What Coral Do You Most Regret Adding to Your System?

[nickkohrn]

As the title says, what coral do you most regret adding to your system?

Why do you regret your decision?

What would you tell a new hobbyist about that coral that you did not know before purchasing it, if anything?

Back in the day when I first started out, I had a very empty 75. Like all new tank owners, I was very excited to get some coral in there. A "friend" gave me a small colony of nuclear green palythoa. Well, the colony grew like a weed and didn't stay small for long. It started overgrowing a couple of chalices, grrr. Thing took a majano wand like a champ, and just kept coming back. I am older and hopefully wiser now. Quality over quantity is my new mantra.

Green Star Polyps!

Once they get growing, The grow over EVERYTHING!
Invasive little buggers.

Aiptasia

 

[Reefltx]

Encrusting purple porite, got it from Copps years ago as a freebie. 2yrs later I had to remove the whole rock. Nothing can stand in its way.

Kenya Tree - drops branches to spread throughout tank.

We got some bubbletip anemones from @Lasse and put them in our 10000 litre reef tank at work. That was a bad idea Now they spread everywhere amongst the SPS corals, and burn everything in their way. And not easy to get out.. So if you know a fish eating only bubbletip anemones, please let me know!

So thank you Lasse!

Aiptasia

I remember feeding Aiptasia in my first saltwater aquarium because I just thought it was a coral. I fed it shrimp, and it wouldn’t stop growing.

What a n00b.

Blue Sympodium.... It is still everywhere.....

+ 1 on the Regular Kenya tree.

Love the neon green Kenya tree. Can't get that to drop babies yet.

When I first started my second tank (on my third now) I made the mistake of adding these buggers. I ultimately removed half of my live rock to rid the system of it.

I just searched for Blue Sympodium photos. It’s a beautiful coral. It’s too bad that it’s was/is so invasive for you.

Two corals are the biggest "pretty now watch what I'll do to your tank later" :
1-Blue Polyps;
2-Xenia

Memorable performances
-GSP
-Kenia Trees
-mushrooms

Cyphastria

 

[Salt Creep]

Cyphastria. I put a frag on a rock and it killed every acro it touched. Not something you can easily remove either without taking the rock out.

It’s a must have for me, but it is given its own rock or back wall

 

[Rakie]

I'm very lucky -- I learned that lesson in middle school LOL! Otherwise, way back then it would have been Xenia and cloves.

 

[pecan2phat]

Montipora Spongodes.
I let it spread on my bare bottom and it eventually grew up the front display panel.
Tank is shut down but that skeletal remains is still stuck on the glass and is permanent now!

GSP, and, fortuitously, only GSP.
